NI 333 Earth leakage clamp
626005024Summary
At first, the NI 333 looks like a normal current clamp. Nevertheless, the special integrated technique of the jaw enables the user to measure very low or differential currents. The NI 333 is designed with an ergonomic housing with a wide jaw (opening). With this jaw, conductors up to 30 mm can be measured easily.
The jaw of the clamp is very sensitive, yet very well isolated. This enables the user to measure not only within the standard frequency of 50/60 Hz, but also at higher frequencies. In order to filter the disturbance of high frequencies, a special filter has been developed. This widens the range from 40 Hz up to 1 kHz. All measured values are displayed on the LCD screen.
